    The ion exchange capacity of the clays is the property by which clay minerals attract available ions from their surroundings and retain them in an exchangeable state. These ions can be exchanged with other ions and anions during treatment from ions in a water solution. These ion exchange reactions generally do not affect the structure of the clay mineral. Ion .

  • HEAVYMETAL UPTAKE BY A HIGH CATIONEXCHANGECAPACITY .

    Sodium exchange samples were prepared by immersing the clay into 1M solution of sodium chloride. Cation exchange was complete by washing and centrifuging four times with sodium chloride. Then, the samples were transfered into dialysis tubes in order to obtain chloride free clays and dried at room temperature.

  • exchange capacity sentence in Hindi

    From the soil chemist's perspective, the process improves the ionexchange capacity of soils while forming new clay minerals. This reflects an increase in the level of soil organic carbon, Cationexchange capacity, available plant nutrients and exchangeable bases. The total number of ions a soil can hold, its total negative charge, is the soil's ion exchange capacity. .

  • Cation Exchange Capacity (CEC)

    Cation Exchange Capacity (CEC) Cation exchange capacity (CEC) is defined as the sum total of the exchangeable ions that a soil can adsorb. Exchangeable ions are positively charged ions (, Na+, Ca2+, K+) held on or near the negatively charged surfaces of soil particles and which may be replaced by other positively charged ions in the ...
